Abstract[English]
A method includes sending, by an access point (AP) to one or more stations (STAs), a request for channel state information (CSI). The request includes a null data packet announcement (NDPA) frame including a common information field. The common information field including an indicator of whether trigger based (TB) sounding or non-trigger based (non-TB) is being used. Then, the method includes receiving, by the AP from the one or more STAs, a CSI feedback response based on the request. The common information field may be a null data packet announcement (NDPA) variant field in an alternative name and the indicator may utilize 1 bit.[French]
Un procédé consiste à envoyer une demande d'informations d'état de canal (CSI) à une ou plusieurs stations (STA) au moyen d'un point d'accès (AP). La demande comprend une trame d'annonce de paquet de données nul (NDPA) comprenant un champ d'informations commun. Le champ d'informations commun comprend un indicateur mentionnant si un sondage basé sur un déclencheur (TB) ou non basé sur un déclencheur (non TB) est utilisé. Ensuite, le procédé consiste à recevoir au moyen de l'AP, en provenance de la ou des STA, une réponse de rétroaction de CSI d'après la demande. Le champ d'informations commun peut être un champ de variante d'annonce de paquet de données nul (NDPA) dans un nom alternatif, et l'indicateur peut utiliser 1 bit.
